Immutability by default

Partially pure functions

C/C++ translation

V can translate your entire C/C++ project and offer you the safety, simplicity, and up to 200x compilation speed up. 
std::vector s; s.push_back("V is "); s.push_back("awesome"); std::cout << s.size(); s := [] s << 'V is ' s << 'awesome' println(s.len)Read about translating Doom & Doom 3, LevelDB, SQLite.

Performance

As fast as C

Minimal amount of allocations 

Built-in serialization without reflection 

Hot code reloading

Get your changes instantly without recompiling!
Since you also don't have to waste time to get to the state you are working on after every compilation, this can save a lot of precious minutes of your development time.

Native cross platform UI library

Build native apps that look native. You no longer need to embed a browser to develop cross platform apps quickly.

Run everywhere

V can compile to (human readable) C, so you get the great platform support and optimization of gcc and Clang.
